HENRY R. PALMER, OF SAN DIEGO, CALIFORNIA.

ADVERTISING DEVICE.

To all whom it may concern Be it known that I, HENRY R. PALMER, acitizen of the United States, residing at San Diego, in the county ofDiego and State of California, have invented new and useful Improvementsin Advertising Devices, of which the following is a specification.

This invention relates to advertising devices, the primary objectof theinvention being to provide an advertising device de signed to embodywithin a minimum area a maximum amount of advertising surface.

A further object of the invention is to pro vide an advertising deviceincluding a cas ing and a plurality of rotary drums or cylinders, one ofwhich is positively driven from a source of power, and the other orothers driven by friction therefrom, thus enabling the device to beoperated to successfully display advertising matter upon the cylindersat a minimum cost.

A still further object of the invention is to provide sign bearingcylinders constructed and arranged in a novel manner and provided withfriction bands for communicating motion from one to the other andserving also to provide proper clearance spaces between the cylinders.

The invention consists of the features of construction, combination andarrangement of parts hereinafter fully described and claimed, referencebeing had to the accompanying drawings, in which Figure 1 is a frontelevation of an advertising device embodying my nvention. Fig. 2 is avertical transverse section through a portion thereof. Fig. 3 is avertical front to rear section through the advertising device. Fig. 4:is a detail view of one of the sign bearing cylinders.

Referring to the drawings, the numeral 1 designates an inclosing case orcabinet, preferably of rectangular or oblong rectangular form and havinga suitable transparent front wall, which may be formed by one or morehinged doors 2. Arranged within the casing is a series of horizontaltransverse shafts 3, which are fixed at their ends in the side walls ofthe casing, and on each of these shafts is arranged a sign bearingcylinder or drum t. These cylinders or drums are preferably of likedimensions, and each cylinder is provided with grooved guideways 5 toreceive cards 6 or other removable sign matter. It is to be understood,however, that the surface of the cylinder may Specification of LettersPatent.

be fixed or otherwise formed and that such surface may have theadvertising matter printed, painted or otherwise placed there on. Thisconstruction enables a series of signs to be applied to each cylinder,which are successively exposed in the rotation thereof, and of thecylinders being conveniently detached to change the signs wheneverdesired.

Arranged within the base of the cabinet is an electric or other suitablemotor 7 which is in gear with a vertical shaft 8 carrying a gear member9 which meshes with a gear rim 10 on one end of the cylinder applied tothe lower shaft 3, whereby the lower cylinder is driven. The motor, whenof the electric type, may be supplied with current in any preferredmanner, and in practice a series of electric lamps 11 is provided withinthe casing upon the front wall thereof to illuminate the interiorthereof. These lamps, however, may be mounted upon any other suitableportion of the apparatus. Each drum, as shown, is preferably of skeletonformation, and the signs thereon may be transparent or translucent, sothat the light will shine therethrough.

In order to provide for the transmission of power from the lowercylinder or set of cylinders to each of the others, the cylinders areprovided at their ends with friction bands 12 of rubber or othersuitable material. Thcse friction bands of cylinders on adjacent shaftscontact with each other, for the transmission of power from one to theother, and said friction bands also serve to space the cylindersdefinitely with relation to each other, so as to provide for the freeclearance of the sign cards between adjacent cylinders, in the event ofthe projection of the same from any cause beyond the faces of thecylinders. Thus it will be seen that it is necessary with myconstruction to transmitpower directly to only one cylinder, the othersbeing frictionally driven therefrom, whereby economy of construction andoperation is insured. If desired, the top and bottom portions 13 and itat the front of the cabinet may consist of short fixed walls adapted tosupport stationary advertising matter and to conceal the spaces betweenthe top and bottom walls of the cabinet and the top and bottomcylinders.

I claim 1. An advertising device comprising a casing, a series of signbearing cylinders rotatably mounted therein, said cylinders beingprovided with friction bands for the transmission of power to eachother, and means for communicating driving power to one of saidcylinders.

2. An advertising device comprising a casing, a series of superposedhorizontal transverse shafts therein, cylinders revolubly sup ported bythe respective shafts, said cylinders being provided with friction bandsfor the transmission of power to each other, and means for transmittingmotion to one of said cylinders.

3. An advertising device comprising a cas ing, a series of superposedhorizontal transverse shafts arranged therein, drums or cylinderssupported by said shafts and provided with friction bands fortransmitting power to each other, motor driven means for operating oneof said cylinders, and illuminating means upon said casing.

4. An advertising device comprising a casing having a transparent front,a series of skeleton drums arranged within said casing and provided withfriction bands for the transmission of power to each other, means forcommunicating motion to one of the drums, transparent signs carried bythe skeleton drums, and illuminating means upon the casing.

5. An advertising device comprising a cabinet having a front wallcomposed of fixed top and bottom sections and an intervening transparentsection, illuminating means upon the casing, skeleton drums within thecasing, transparent sign elements carried by the drums, friction bandsupon the drums for transmitting motion from one to the other, and meansfor positively driving one of the drums.

In testimony whereof I affix my signature in presence of two witnesses.
